Here are the names of all the notes on the guitar fretboard up to the 12th fret in standard tuning plus the most prominent (and usable) natural harmonics locations. All notes fretted above the 12th fret are an octave higher than the corresponding note located 12 frets lower on the same string so have the same names.
Non-natural notes can be named either by their sharp name or flat name, e.g., C sharp or D flat, provided there's no musical context involved. If there's a musical context, the note will be named depending on factors such as the key of the music.
If you're unfamiliar with playing natural harmonics on the guitar, they're produced by lightly touching any guitar string with your fretting-hand finger tip over the specified fret. Don't press down - just touch it lightly. Then pluck the string (with any picking-hand finger) and immediately release your fretting-hand finger from the string and the harmonic will ring out with its distinctive tone. Don't place your finger just behind the fret like you do when fretting a note. Your finger must be touching the string exactly above the fret metal. Don't be too slow in removing your finger or it will mute the harmonic and prevent it from ringing out clearly. Don't be too quick either or all you'll hear is the open string ringing out. Bass strings at the 12th & 7th frets are the easiest to work with and practise on.
Harmonics In Guitar Tablature
Natural harmonics occur at exact divisions (nodes) of the length of the vibrating string. Those that are useful to guitarists (easy to produce and tuneful) are those that occur at:
Each division produces an audible harmonic which is a multiple of the fundamental frequency (vibration rate) of the open string. That means every open string has its own set of harmonics, but they all share the same fret locations regardless of string and also regardless of tuning. An altered guitar tuning such as DADGAD will have its unique set of harmonics occurring above exactly the same frets as in standard (or any) tuning.
The harmonic produced at fret 12 on that string has a frequency of twice that, or 220 Hz, so we hear it as the A one octave higher in pitch. It has the same pitch as the fretted note at fret 12.
The Harmonic Minor Scale
The harmonic produced at fret 7 has a frequency that is three times higher (330 Hz) and we hear that as E - a perfect 5th plus an octave higher than the open 5th string.
The harmonic produced at fret 5 has a frequency that is four times as high as the open 5th string, i.e., 440 Hz - which is the note A, two octaves higher than the open 5th string.
The identical harmonics produced at frets 4 and 9 have a frequency that is five times as high as the open string, i.e., 550 Hz - which is the note C sharp - the same pitch as the fretted note on string 1 fret 9.
How To Play A Pinch Harmonic On Guitar
Other harmonics can be found closer elsewhere on the string, but they aren't so easily produced as they don't line up as closely with the frets as the ones above. Nor are they very accurate or loud. Acoustic guitarists don't have much use for those, but with an electric guitar, plus the help of amplification and electronic processing such as distortion or multi-effects foot-pedals, etc., can achieve impressive musical sounds when playing those more obscure harmonics.
In physics, the fundamental pitch (the open string in the case of guitar's natural harmonics) is called the first harmonic. For many guitarists, however, the first harmonic of each string is the lowest pitched one that can be produced as a sweet-sounding harmonic, i.e., the 12th fret harmonic. The numbers aren't important, but it's very useful to memorise the intervals that each produces with the open string. Regardless of string or tuning, the intervals never change.
Harmonics above the first harmonic or fundamental are also referred to as overtones. So the 1st overtone corresponds with the 2nd harmonic, the 2nd overtone with the 3rd harmonic, and so on.

Guitars, and most other modern Western Instruments, follow the tuning standard known as equal temperament. In equal temperament, semitones are defined as being exactly one twelfth of an octave, which (as before) is defined as a 2:1 pitch relationship.
Guitar frets are laid on the fretboard according to this system, which is why the octave above any open string is exactly twelve frets higher. What it also means is that, apart from the octave, all harmonics will sound very slightly different in pitch from the equivalent fretted notes. The harmonics haven't changed, of course, but the fret placements have. Laying the frets so that each fret (or semitone) is exactly one twelfth of an octave higher than its neighbour means that most of the fretted notes will be slightly different from the harmonic at that fret. Only the octave (12th fret) note will exactly agree with the harmonic.
For example, the harmonic produced on fret 4 of the 6th string (G#) will sound slightly different from the G# fretted note on string 1 fret 4. The exact locations of the harmonics (again, apart from the 12th fret) will also differ very slightly from the fret placement. For the important harmonics mentioned above, the difference in pitch goes unnoticed by most people including professionals, and as the difference in location is smaller than the width of a fingertip, it can be ignored for most playing purposes.This article needs additional citations for verification.

Things To Know About Playing Natural Harmonics
Playing a harmonic on a string. Here, +7 indicates that the string is held down at the position for raising the pitch by 7 semitones.
Playing a string harmonic (a flageolet) is a string instrumt technique that uses the nodes of natural harmonics of a musical string to isolate overtones. Playing string harmonics produces high pitched tones, oft compared in timbre to a whistle or flute.
Overtones can be isolated by lightly touching the string with the finger instead of pressing it down against the fingerboard (without stopping).

For some instrumts this is a fundamtal technique, such as the Chinese guqin, where it is known as fan yin (泛音, lit. floating sound), and the Vietnamese đàn bầu.
Wh a string is plucked or bowed normally, the ear hears the fundamtal frequcy most promintly, but the overall sound is also colored by the presce of various overtones (frequcies greater than the fundamtal frequcy). The fundamtal frequcy and its overtones are perceived by the lister as a single note; however, differt combinations of overtones give rise to noticeably differt overall tones (see timbre).
Above, the lgth fraction is the point, with respect to the lgth of the whole string, the string is lightly touched. It is expressed as a fraction n / m , where m is the mode (2 through 16 are giv above), and n the node number. The node number for a giv mode can be any integer from 1 to m − 1. However, certain nodes of higher harmonics are coincidt with nodes of lower harmonics, and the lower sounds overpower the higher ones. For example, mode number 4 can be fingered at nodes 1 and 3; it will occur at node 2 but will not be heard over the stronger first harmonic. Ineffective nodes to finger are not listed above.

Wh a string is only lightly pressed by one finger (that is, isolating overtones of the op string), the resulting harmonics are called natural harmonics. However, wh a string is held down on the neck in addition to being lightly pressed on a node, the resulting harmonics are called artificial harmonics. In this case, as the total lgth of the string is shorted, the fundamtal frequcy is raised, and the positions of the nodes shift accordingly (that is, by the same number of frets), thereby raising the frequcy of the overtone by the same interval as the fundamtal frequcy.
What Is Simple Harmonic Motion?
Artificial harmonics are produced by stopping the string with the first or second finger, and thus making an artificial 'nut, ' and th slightly pressing the node with the fourth finger. By this means harmonics in perfect intonation can be produced in all scales.— Grove's Dictionary of Music and Musicians (1879)[5]
Artificial harmonics are more difficult to play than natural harmonics, but they are not limited to the overtone series of the op strings, meaning they have much greater flexibility to play chromatic passages. Unlike natural harmonics, they can be played with vibrato.
